I got a Vega 64 since I wanted to start moving away from the Intel/NVIDIA camp and start moving to the Red team.
I am seeing that when my system goes to sleep a single monitor will not come back (black screen). I can still use the display but I get no actual video until I reboot.
I have tried different ports on the card and the issue follows the monitor. These are 2 identical 4k monitors using Display Port connections.
My current build is an Intel 8700K with the Vega 64.
